THE NEW YOR.KER. had previously compared the dental remains of Second World War soldiers with their dental records, he had learned that men with extraction- only records did not have otherwise perfect teeth. He had learned that two of the forms put in missing-in-action files in the nineteen-forties did not lend themselves to thorough dental charting: the people who filled out these forms could easily record extrac- tions, but there was little room on either form for them to record other dental work that might have been done. The records of only nine of the men on the plane contained dental charts from their years in the armed services which showed fillings, crowns, or other forms of dental resto- ration or treatment as well as extrac- tions. Despite the abundance of informa- tion visible on bones which enables a Tadao Furue to make reliable deter- minations of sex, race, age, height, and muscularity, the information is often not specific enough to lead to a precise identification. According to the bones, the man on X-I could be Charles Barnard, Stanley Gross, or Stanley Lawrence. Personal identifica- tion from skeletal remains is more likely to be accomplished by a study of dentition. The effectiveness of dental identification is naturally related to the recovery of dental remains, which had been limited on Mt. Thumb, and to the calibre of the dental records, which had been dismal for the men on 41081. Furue does not permit himself to be discouraged easily by things in life he cannot change. He goes on with his work. His next task was to compare the dental charts from the remains with the dental charts from the records. In dentistry, each tooth is as- signed a number to simplify its desig- nation. Under the current system used by the armed services, the upper teeth are, from right to left, No. 1 to No. 16. No. 1 is the right third mo- lar (or wisdom tooth), No. 2 is the right second molar, No. 3 is the \ \ \ 57 The · that clocKs the future , \ 12 . 12 \ Ý) \- The n-west sensatIon from SeiP clocy :r10Vementc; and sle,- IstlC de .0T1S make th.
